ARMOGENE ROBICHAUX AND VIILLIABI JOSEPH COLEM'AN, OF NEW IBERIA, LOUISIANA.

WRENCH.

Application filed November T 0 all whom it may concern:

Be it known that we, Amroennn ROBI- c'i-rAUX and VVILLIAN Josnrrr Conmrnzv, both citizens of the United States, residing at New Iberia, in the parish of Liberia and State of Louisiana, have invented certain new and useful improvements in lVre-nches, of which the following is a specification.

This invention relates to wrenches, and has for one of its objects to provide a device of this character which is applicable to nuts of various sizes and to pipes or rods of various diameters, and which may quickly be ad justed to its various sizes without removing any of the parts.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a side elevation of the improved wrench, and opened to its full ca pacity.

Fig. 2 is a side elevation, partly in section, showing the jaws partly closed.

Fig. 3 is a transverse section on the line 33 of Fig. 1.

Fig. 1 is a detached side View, on a reduced scale, of the movable jaw.

The improved wrench comprises a movable jaw including nut or pipe engaging portions 10 and 11 and having a longitudinally directed guideway 12, and a socket 13 communicating with the guideway, as shown in Fig. 2. The sides of the guideway are coupled at their upper ends by transverse spaced bands.

Slidable through the guideway 12 is a stock 14 having lateral jaw portions 15 and 16 cooperating respectively with the jaw portions 10 and 11. The jaw portion 10 and 11 are designed to engage larger nuts, pipes or rods, while the jaw portions 15 and 16 are designed to engage smaller nuts, pipes or rods. The jaw portions 15 and 16 are provided with pipe or rod gripping teeth, as shown.

The stock 14 is reduced laterally intermediate the ,ends, and the reduced portion provided with stop teeth 17 preferably in ratchet form, with which a stop pawl device 18 engages,the latter, preferably spring 9, 1922. Serial No. 599,902.

supported, and pivoted at 19 in a part of the stationary jaw. By this means the stock and its jaw portion 15 and 16 may be locked in adjusted position relative to the stationary aw, as will be obvious, but by forming the teeth 17 in the form shown the movable jaw may be moved inwardly without reference to the pawl.

Pivoted at 20 within the socket 123 is a combined holding lever and handle 21, the latter forked at 2.. to pass upon both sides of the stock 1 1 as shown in Fig. 3, and pivotally united thereto as at 23.

The aperture in the stock 14 for the rivet 23 is slotted transversely of the stock, as

shown at 24 to prevent cramping when the handle is operatec, as will be obvious.

' By this simple arrangement a very effectual wrench is produced capable of operating in a wide range of sizes of nuts, pipes or rods, and may be adjusted to various sizes without detaching any of the parts.

The improved device may be constructed of any suitable material of any suitable size or capacity or in a variety of sizes to suit nuts, pipes or rods of various sizes, as will be obvious.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specifications, but it will be understood that modifications within the scope of the claim may be made in the contruction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention what is claimed as new is:

In a wrench, a body including a jaw and a guideway having spaced side portions and spaced transverse holding bands and with a socket communicating with the guideway, 21. stock slidable through the guideway and having an opposing jaw and reduced laterally intermediate the ends with ratchet teeth in the reduced portion, an operating lever pivoted in the socket and forked to engage the reduced portion of the stock and pivoted thereto, and a stop pawl carried by the body and engaging the ratchet teeth.

In testimony whereof, we affix our signatures hereto. 7
